Note 1: All devices 100% production tested at T

A

= +85°C. Limits over the operating temperature range are guaranteed by design.

Note 2: Treble = bass = 0dB. C

CB_

= open, C

CT

_ = short, left input signal = right input signal = +2V.

Note 3: See Tables 3 and 4 and Figure 7. V

DD

= +2.7V, V

SS

= -2.7V.

Note 4: Guaranteed by design.
Note 5: Measured with A-weighted filter.
Note 6: Supply current measured while attenuator position is fixed.
Note 7: Set _OUT = 0dB and shutdown device SHDN = 0. t

WU

is the time required for _OUT to reach 0dB after SHDN goes high.
